What is aFXS
aFXS simply represents the compounding cvxfxsCrv LP in the Concentrator vault. The total amount of cvxfxsCrv LP contained in the Concentrator vault is equal to the total aFXS balance multiplied by the current index:
cvxfxsCrv_Balance = aFXS_Balance * Current_aFXS_Index
Using aFXS to represent a share of the underlying compounding cvxfxsCrv LP vault simplifies the smart contracts and is more gas efficient.
Is it safe?
The concentrator is built by the experienced and security-obsessed AladdinDAO team, and it is audited by SECBIT Labs. Check out the audit here.
How much does it cost?
Concentrator takes a standard 10% fee on yields only, during the harvest process. Concentrator’s fees are shared between CTR lockers and the Concentrator treasury. Each vault has a withdrawal fee, which is specified per-vault. Withdrawal fees are distributed to other depositors in the vault (not to token lockers or the treasury).
